<p>
A generic model representing the track x time grid of patterns of a song.
Can be shown by a treeview.

The visible length can be greater then the real length of the underlying
sequence, by setting the BtSequenceGridModel::length property.

<p>
Creates a grid model for the <em class="parameter"><code>sequence</code></em>. The model is automatically updated on
changes in the content. It also expands its length in sync to the sequence.
</p>
<p>
To make the row-shading work, the application has to update
<a class="link" href="BtSequenceGridModel.html#BtSequenceGridModel--bars" title='The "bars" property'><span class="type">"bars"</span></a> when it changed on the view.
</p>
<p>
When setting <a class="link" href="BtSequenceGridModel.html#BtSequenceGridModel--length" title='The "length" property'><span class="type">"length"</span></a> to a value greater than the real
<em class="parameter"><code>sequence</code></em>, the model will append dummy rows. This allows the cursor to go
beyond the end to expand the sequence.
